I don't think there's any reason for me to post pics. I've even got the same color van as yours so they would look identical.
I did run a very scientific test today to see how well the vents worked. I ran the van till it was hot and while going down the road at 55mph had my wife lean out, OK WAY out, the window and feel the vent. She said she didn't feel any warm air. After I stopped, I felt the vent and didn't get any warm air coming out either. So, me thinks it's just a bitchin looking mod without much real benefit. Don't forget, I did not enlarge the inner fender as did jwintersteller.
I would do it again just for the looks. Besides, it now goes faster on less fuel too....
